Now we see through a glass, darkly...
From this world to that which is to come.
The expression to see "through a glass" (or a mirror) "darkly" means having an opaque or limited vision of our existence in this world as we aware of it in this point in time. Our sense of what is real is obscured by what we know in the dimension of reality that we are limited to presently. Only through enlightenment in an extension outside of the one we exist in now will we see clearly the true meaning of life and a higher power greater than ourselves. It is rooted in the Biblical writings of Paul in the New Testament.
For we know in part, and we prophesy in part; but when the perfect comes, the partial will be done away. When I was a child, I used to speak as a child, think as a child, reason as a child; when I became a man, I did away with childish things. For now we see in a mirror dimly, but then face to face; now I know in part, but then I shall know fully as I also have been fully known. But now abide faith, hope and love; but the greatest of these is love. [1 Corinthians 13: 9-13 New American Standard 1977 edition]
Personally I know where my beliefs are and where they will lead me. Although my point of reference is what I have been taught combined with my spiritual experiences I do not limit the power of God and what He may see fit for other people and their view of enlightenment. This is antithetical to what many believe, those who believe in only one way. I only see in part and not yet face to face nor know fully therefore I reserve my judgment. I do believe that the overarching principle is love and to me that also means optimism for the future and thinking positively. Everyone is at different paths and points on the continuum of personal growth and I have faith in my hope that everyone will reach their own destination in peace, love and understanding.
